1 INTRODUCTION
This document details the installation and operation requirements of the DSE6110 MKII & DSE6120
MKII modules, part of the DSEGenset® range of products.
The manual forms part of the product and should be kept for the entire life of the product. If the
product is passed or supplied to another party, ensure that this document is passed to them for
reference purposes.
This is not a controlled document. DSE do not automatically inform on updates. Any future updates of
this document are included on the DSE website at www.deepseaplc.com
The DSE61xx MKII series is designed to provide differing levels of functionality across a common
platform. This allows the generator OEM greater flexibility in the choice of controller to use for a
specific application.
The DSE61xx MKII series module has been designed to allow the operator to start and stop the
generator, and if required, transfer the load to the generator either manually or automatically.
Additionally, the DSE6120 MKII automatically starts and stops the generator set depending upon the
status of the mains (utility) supply.
The user also has the facility to view the system operating parameters via the text LCD display.
The DSE61xx MKII module monitors the engine, indicating the operational status and fault conditions,
automatically shutting down the engine and giving a true first up fault condition of an engine failure by
the text LCD display.
The powerful ARM microprocessor contained within the module allows for incorporation of a range of
complex features:
Text based LCD display
True RMS Voltage
Current and Power monitoring
USB Communications
Engine parameter monitoring.
Fully configurable inputs for use as alarms or a range of different functions.
Engine ECU interface to electronic engines.
Data Logging
Using a PC and the DSE Configuration Suite software allows alteration of selected operational
sequences, timers, alarms and operational sequences. Additionally, the module’s integral front panel
configuration editor allows adjustment of this information.
Access to critical operational sequences and timers for use by qualified engineers, can be protected
by a security code. Module access can also be protected by PIN code. Selected parameters can be
changed from the module’s front panel.
The module is housed in a robust plastic case suitable for panel mounting. Connections to the module
are via locking plug and sockets.

2.6.1 VA RATING OF THE CTS
NOTE: Details for 4 mm² cables are shown for reference only. The connectors on the DSE
modules are only suitable for cables up to 2.5 mm².
The VA burden of the module on the CTs is 0.25 VA. However depending upon the type and length of
cabling between the CTs and the module, CTs with a greater VA rating than the module are required.
The distance between the CTs and the
measuring module should be
estimated and cross-referenced
against the chart opposite to find the
VA burden of the cable itself.
If the CTs are fitted within the
alternator top box, the star point
(common) of the CTs should be
connected to system ground (earth) as
close as possible to the CTs. This
minimises the length of cable used to
connect the CTs to the DSE module.
Example:
If 1.5 mm² cable is used and the
distance from the CT to the measuring
module is 20 m, then the burden of the
cable alone is approximately 15 VA.
As the burden of the DSE controller is
0.25 VA, then a CT with a rating of at
least 15 VA + 0.25 VA = 15.25 VA
must be used. If 2.5 mm² cables are used over the same distance of 20 m, then the burden of the
cable on the CT is approximately 7 VA. CT’s required in this instance is at least 7.25 VA (7 + 0.25).

2.6.2 CT POLARITY
NOTE: Take care to ensure correct polarity of the CT primary as shown above. If in doubt,
check with the CT supplier.
Take care to ensure the correct polarity of the CTs. Incorrect CT orientation leads to negative kW
readings when the set is supplying power. Take note that paper stick-on labels on CTs that show the
orientation are often incorrectly placed on the CT. It is more reliable to use the labelling in the case
moulding as an indicator to orientation (if available).
To test orientation, run the generator in island mode (not in parallel with any other supply) and load
the generator to around 10 % of the set rating. Ensure the DSE module shows positive kW for all
three individual phase readings.

Polarity of CT Primary
2.6.3 CT PHASING
Take particular care that the CTs are connected to the correct phases. For instance, ensure that the
CT on phase 1 is connected to the terminal on the DSE module intended for connection to the CT for
phase 1.
Additionally ensure that the voltage sensing for phase 1 is actually connected to generator phase 1.
Incorrect connection of the phases as described above results in incorrect power factor (pf)
measurements, which in turn results in incorrect kW measurements.
One way to check for this is to make use of a single-phase load. Place the load on each phase in turn,
run the generator and ensure the kW value appears in the correct phase. For instance if the load is
connected to phase 3, ensure the kW figure appears in phase 3 display and not in the display for
phase 1 or 2.
2.6.4 CT CLASS
Ensure the correct CT type is chosen. For instance if the DSE module is providing over current
protection, ensure the CT is capable of measuring the overload level required to protect against, and
at the accuracy level required.
For instance, this may mean fitting a protection class CT (P15 type) to maintain high accuracy while
the CT is measuring overload currents.
Conversely, if the DSE module is using the CT for instrumentation only (current protection is disabled
or not fitted to the controller), then measurement class CTs can be used. Again, bear in mind the
accuracy required. The DSE module is accurate to better than 1% of the full-scale current reading. To
maintain this accuracy, fit a Class 0.5 or Class 1 CT.
Check with the CT manufacturer for further advice on selecting CTs Inputs

2.7.4 CHARGE FAIL INPUT
The charge fail input is actually a combined input and output. Whenever the generator is required to
run, the terminal provides excitation current to the charge alternator field winding.
When the charge alternator is correctly charging the battery, the voltage of the terminal is close to the
plant battery supply voltage. In a failed charge situation, the voltage of this terminal is pulled down to
a low voltage. It is this drop in voltage that triggers the Charge Failure alarm. The level at which this
operates and whether this triggers a warning or shutdown alarm is configurable using the DSE
Configuration Suite Software.
